When I was young,my father ,who always taught me how to be a true man,told me that it is essential to be tolerant in your life whatever happens. And that remains the most valuable present he gave me,I think To be tolerant, I need to keep calm when great trouble lies in front of me,however difficult it is to overcome it; To be tolerant ,I need to resist the temptation of all kinds of the outside world,even if it is so attractive; To be torlerant, I need to pull myself(控制自己情绪) in times of extreme sorrows and joys, no matter how they affect me.
